Ludo (libretro frontend) VS Nebula

A similar project is Ludo [1] which is part of the libretro family. More for emulation but really a clean UI (it actually has screenshots) [1]: https://ludo.libretro.com/#about. - Source: Hacker News / 9 months ago

Linux Mint is fine. You'll want to modify it to start using something lighter than Cinnamon (I suggest OpenBox); 4GB of RAM means that KDE and GNOME/Cinnamon are not going to be fun, and as you're using it for arcade games, you don't need much more than a launcher for Steam/RetroArch/EmulationStation/Ludo/Lutris/etc. Source: 11 months ago

MULTI EMULATORS (basically one program that handles a bunch of consoles) I would advise you to avoid frontend or multi emulators like mame or retroarch, Because they could be intimidating if you start in this area To start with a frontend multi emulator, I recommend this one witch is beginner friendly and have a good documentation Ludo emulator.

There's a spin-off of Retroarch that I think is way better called Ludo. It's basically a less confusing version of Retroarch with a really clean UI! Source: over 1 year ago

Some standalone emulators: For Dreamcast you can try https://redream.io/ Since the original SF3:TS was on an try CPS3 1.0a here http://nebula.emulatronia.com/. Source: about 2 years ago

Use the standalone "Model 2 Emulator" (http://nebula.emulatronia.com/) instead. It can use Direct3D to upscale internal rendering resolution for sharper image: https://i.postimg.cc/1XN6qWmM/House-of-the-Dead-M2emulator.png. Source: about 2 years ago
